A motor control device includes: a target value acquisition part acquiring a target value of a control parameter of a motor; an operation amount calculation part calculating an operation amount; an output acquisition part acquiring an output of the control parameter; and a deviation calculation part calculating a deviation between the target value and the output. The operation amount calculation part includes: a first calculation part calculating a first value corresponding to the deviation; a second calculation part calculating a second value in a range not exceeding a predetermined upper limit value based on an integrated value of the deviation; and a third calculation part calculating the operation amount in a range not exceeding an operation amount upper limit value based on the first and second values. The predetermined upper limit value is larger than a value obtained by subtracting the first value from the operation amount upper limit value.
A motor control device according to the disclosure includes: a current control part, performing current control for rotating a motor from a stop state; a rotation speed calculation part, calculating an actual rotation speed of the motor; an acquisition part, acquiring a target rotation speed of the motor; a speed control part, performing speed control of the motor, so that the actual rotation speed of the motor becomes the target rotation speed; and a correction part, at a time when a current control state is transitioned to a speed control, correcting the target rotation speed based on a relation between the actual rotation speed and the target rotation speed. When the target rotation speed is corrected, the speed control part performs the speed control so that the actual rotation speed becomes the target rotation speed corrected by the correction part.

[Problem] To provide a brushless motor, and a manufacturing method thereof, in which a stator coil winding can be easily connected to an external circuit, and which does not require a complex configuration. [Solution] A power supply structure comprises, for each phase, a winding pair comprising a first lead part of a winding and a second lead part of the winding, a guide part which guides each of the winding pairs, and a connection part where the first lead part and the second lead part are electrically connected, wherein the winding pairs include a first portion which is guided by a guide part, and a second portion which, from the axially outside end of the first portion, is bent along the surface of a bracket; the first portion passes through a through-hole in the axial direction and the second portion extends up to the connection part.
The present invention provides a drive unit and a method for attaching the same with which it is possible to improve the ease of attaching the drive unit to an attachment object. A limiting member is configured so as to limit the rotation of a drum when a lock member has fixed a pulley in a first position, and to allow rotation of the drum when a coil spring has caused the pulley to move to a second position. This makes it possible to prevent rotation of the drum in the state (vehicle mounting preparation state) before attaching the drive unit to a vehicle body. Therefore, it is possible to prevent a pair of cables from loosening inside a drum housing and catching on other constituent components. Accordingly, it is possible to improve the ease of attaching the drive unit to a vehicle body.

The small-diameter part is exposed outside the gear case. The dimensional accuracy (dimensional tolerance ±α) of the external diameter of the small-diameter part is enhanced. The small-diameter part can be set, without rattling, in a lower mold for molding the gear case. Consequently, the support shaft can be accurately and consistently provided to the gear case. Because the large-diameter part and the step part are embedded in the gear case, the resistance of the support shaft against pulling from the gear case can be enhanced.

Disclosed is a vehicular opening/closing body control device including: a positional information acquisition; a storage part; and a motor control part. The motor control part includes: a drive start part that operates the motor based on the positional information so that the opening/closing body in a stopped state is moved; and a drive part that performs feedback control of the motor based on the positional information and the target value so that the movement speed of the opening/closing body which has been started to move by the drive start part reaches the target value. The drive start part generates a first output in the motor when the opening/closing body is at a first position, and generates a second output smaller that the first output in the motor when the opening/closing body is at a second position closer to a fully closed position than the first position.
The present invention reduces unstable motion of a motor during deceleration of the motor revolution speed. The present invention has: a plurality of sensors that each detect the rotary position of a rotor and output a position detection signal; a speed-of-revolution determination unit that determines whether or not the speed of revolution of a brushless motor is equal to or lower than a predetermined threshold, on the basis of the position detection signals; and a motor control unit. A current conduction control unit provided to the motor control unit uses, between a first mode and a second mode, different signals serving as a trigger for the current conduction timing of each phase. In the first mode, the current conduction timing to the second phase is advanced relative to the timing at which the position detection signal of a first sensor is turned on. In the second mode, the current conduction timing to the second phase is retarded relative to the timing at which the position detection signal of the first sensor is turned on.
